    • The blurring determination device references image data in which are recorded coefficients that are obtained when pixel values forming the image in the spatial domain are converted to the frequency domain, and detects edges oriented in two or more directions, from among the image data, by comparing a series of the coefficients in each of the directions with various types of basic edge patterns whereby typical gradient patterns of the changes in pixel values are represented by values corresponding the coefficients. The representative values of the width of the detected edges is determined in each of the directions, and the image data is determined to not be blurred when the representative values meet the condition of being at or below a certain threshold.

    • A printer fetches a horizontal direction DCT coefficient group and a vertical direction DCT coefficient group for each block from the JPEG data. The printer selects edge patterns similar to the brightness changes expressed by these coefficient groups from a specified table, and records those pattern numbers in a RAM. The printer judges whether or not the brightness changes of the blocks with each other adjacent are continuous based on the pattern number of each block recorded in the RAM. And by connecting the edge patterns when those brightness changes are continuous, the printer accumulates the blur widths that exist extending over the blocks. Then, based on this cumulative value, the printer determines the presence or absence of image blur. It is possible thereby to detect with good precision the blur of images even for high resolution images while reducing the used memory capacity.
    • 打印机从JPEG数据中取出每个块的水平方向DCT系数组和垂直方向DCT系数组。 打印机从指定的表中选择与这些系数组所表示的亮度变化类似的边缘图案,并将这些图案号记录在RAM中。 打印机基于记录在RAM中的每个块的图案号来判断彼此相邻的块的亮度变化是否连续。 并且通过连接边缘图案,当这些亮度变化是连续的时,打印机会累积存在于块上的模糊宽度。 然后,基于该累计值,打印机确定图像模糊的存在或不存在。 因此,即使对于高分辨率图像也可以精确地检测图像的模糊,同时减少了所使用的存储器容量。

    • With a minimal process load, to determine level of the image of an image data file, for image data files of a format that saves images in the form of coefficients of discrete frequency components. Image data that includes a plurality of coefficients representing the pattern of change of color of the image are acquired (Step S10). Multiple sets of basic pattern data that respectively include a plurality of basic coefficients representing basic patterns of color change are prepared. Then, based on a comparison of the two, one set of selected basic pattern data is selected from among the multiple sets of basic pattern data (Step S20). Subsequently, the blur level of the image of the image data is calculated, based on the basic blur level associated with the selected basic pattern data (S30-S70).
